Ergodic Simulations for Diffusion in Random Velocity Fields
Ergodic simulations aim at estimating ensemble average characteristics of diffusion in random fields from space averages. The traditional approach, based on large supports of the initial concentration in general fails to obtain ergodic simulations. However, such simulations, using single realizations of the velocity, are shown to be feasible if space averages with respect to the location of the initial concentration support are used to estimate ensemble averages.
